FeelFish 3.0 Released - Novel Writing Officially Enters the Multi-Agent Era

While AI is still helping you revise a single line of dialogue through "single-agent Q&A,"FeelFish is already thinking about a bigger question:If every creative step had its own dedicated AI expert on hand, what would writing become?

Today, the answer is here.

FeelFish 3.0 is built on the industry's most cutting-edge MCP, multi-agent collaboration, and reusable Skill system, bringing more than just feature updates—it's a leap in creative paradigm, bringing "agent collaborative writing" from concept to every author's desktop.

Meet the new triangle: Solutions, Agents, Skills

The underlying logic of FeelFish 3.0 revolves around three core concepts. Understand them, and you hold the key to building your own exclusive creative workflow.

Solution

Solutiondetermines "which agents are used in the current conversation, who leads, and who assists." Switching solutions means switching an entire set of agents, with no need to change settings one by one.

• Built-in solutions: "Professional Assistance," "Multi-Agent," "Intelligent Planning," "Game Adventure," etc., ready to use out of the box;
• Custom solutions: automatically generated after selecting a combination in the agent panel, with configurations saved in the project .feelfish directory, effective only for the current project;
• Marketplace solutions: download solutions shared by others from the resource marketplace and apply them with one click.

Agent

Agentis an AI role that performs specific tasks. Each agent has its own system prompt, available tools, and associated skills.

• Main agent: responsible for coordinating the overall situation, intelligently deciding whether to delegate a task to a more specialized sub-agent based on its own settings and the sub-agent's description;
• Built-in agents: professional assistance, planning, creation, polishing, review, etc. They cannot be deleted, but can be enabled/disabled in the current project and configured with skill overrides;
• Custom agents: write role behavior and taboos in Markdown, save the configuration as .feelfish/agents/<id>.md, and associate any skills.

Skill

Skillis a reusable "instruction document" that can be used by multiple agents, describing a certain type of writing specification, style, or process. Agents read skill content on demand during runtime, making every piece of your creative experience truly "take effect."

• Skills use SKILL.md as the main file, stored in .feelfish/skills/<技能名>/；
• Each skill has name(skill identifier) and description(brief description), for agents to determine whether to invoke it in the current task;
• Supports local import and sharing to the resource marketplace, with one-click reuse within the team.

No longer one AI fighting alone

The problem with traditional AI writing tools is that a single model has to simultaneously serve as outline planner, style consultant, polishing editor, and logic reviewer, resulting in each role only achieving 60 points.

FeelFish 3.0's multi-agent solution lets you assemble a professional team

• Planning agent: responsible for world-building and chapter outlines;
• Creation agent: focused on main text generation;
• Polishing agent: polish the texture of the writing and remove the AI feel;
• Review Agent: checks for logical gaps and contradictions.

Four experts, each with their own role, work together to complete your manuscript. The main agent is like an experienced editor-in-chief—it knows when to hand the article over to a columnist instead of taking on everything itself.

Turn creative experience into reusable wisdom

Every mature author has their own set of writing principles. In the past, this experience lived only in your head; now, it can becomeSkills, ready to be called upon at any time by each of your agents.

Creating a skill is very simple: create a new one in the Skills tab, write the standards in Markdown, and then check it in the agent's Associated Skills. You can also import existing documents from your local device, or visit the resource marketplace to see experience shared by other authors.

Build your own exclusive creation pipeline in five steps

• Choose a built-in solution and run through a complete workflow once: Start from the Multi-Agent or Professional Assistance solution, get a feel for the rhythm of agent collaboration, and find your starting point.

• Create 1–2 core skills: Organize the creation standards you care about most into skill documents: outline format, character card templates, style taboos—write them once and reuse them forever.

• Associate skills with the corresponding agents: Let the right experts read the right manuals, avoiding the need to re-teach the AI every time.

• Create custom agents as needed:If the built-in roles are not enough, create dedicated agents: a planner who only writes outlines, an editor who specializes in dialogue polishing. Use Markdown to clearly write their code of conduct and taboos.

• Share to the marketplace, or draw inspiration from it:Browse solutions, agents, and skills shared by others and apply them with one click; or publish your own results so more authors can benefit.

💡 Tip: There is no need to create a separate solution—just select who to use and who is the lead in the agent panel, and a custom solution will automatically form.

Technical foundation: MCP makes agents truly get moving

FeelFish 3.0 is based on MCP（Model Context Protocol） best practices. Agents do not just reply in a chat box. They can read files, call tools, retrieve knowledge base content as needed, and execute creative tasks in a real project directory.

All configurations, skill files, agent definitions, and solution combinations are stored in plain-text Markdown in the project .feelfish directory, version-controllable, migratable, and shareable with your team. Your creative workflow truly belongs to you.

FeelFish 3.0 is now officially released, and all multi-agent and skill features are available in version 3.0.0 and above.
